This article describes the installation of a Centrex Telephone system at Seattle's Sea-Tac International Airport, and the new ultra high-speed passenger information boards going into the new terminals at Newark International Airport. Seattle's Centrex system is backed by the latest electronic switching technology (the equipment is installed in a central office). Called ATS (Airport Telecommunications system), the new setup can provide on a single line, the same functions that formerly required a number of different services. The airport's tenants report a number of operations benefits. Not only has ATS improved operations but has also reduced costs for overall telephone services. Newark's "Real-Time" passenger information board consists of an electronic flap display system that causes all boards to act like a normal video character generator. The format of the character generator on the large board displays is composed of alphaunumeric or wide flap modules; changes in characters are accomplished by the adaptation of the pulse code modulation (PCM) integrated logic circuits for both transmitter and the receivers used throughout the system.
